Best Things to Do in Koh Lanta: Beaches, Snorkelling, Hikes & More

Before visiting Koh Lanta, I expected beaches and a fairly relaxed week. Instead, I found one of the most varied islands I explored in Southern Thailand.

Koh Lanta is a large island with long beaches, jungle trails, mangroves, viewpoints and the unique atmosphere of Koh Lanta Old Town.

There is plenty to explore independently, especially if you enjoy road trips and nature.

It is also an excellent base for adventures further offshore. You can snorkel around Koh Rok, dive at Koh Haa or take an island-hopping trip towards the Trang islands and Emerald Cave.

I spent a week exploring Koh Lanta by moped, and there was always somewhere new to discover.

In this guide, I’ll share the best things to do in Koh Lanta, which experiences I’d prioritise, and how to make the most of your time on the island.

Quick Answer: What Are the Best Things to Do in Koh Lanta?

The best things to do in Koh Lanta combine beaches, exploring the island by road, nature and boat trips to the surrounding islands.

If it’s your first visit, these are the experiences I’d prioritise:

1. Beach-hop along Koh Lanta’s west coast
2. Explore Koh Lanta by scooter or private driver
3. Take a snorkelling trip to Koh Rok and Koh Haa
4. Visit Mu Ko Lanta National Park
5. Explore Koh Lanta Old Town
6. Take a Four Islands and Emerald Cave tour
7. Go diving or snorkelling at Koh Haa
8. Kayak around Koh Talabeng and Koh Phee
9. Explore the Tung Yee Peng mangroves

Only have three days? Spend one day exploring Koh Lanta, one day on the beaches and one day on the water.

Visit Mu Ko Lanta National Park

At the southern end of Koh Lanta, Mu Ko Lanta National Park is worth visiting for its coastal scenery, forest and the lighthouse at Laem Tanod.

You don’t need a full day here. Allow a few hours to walk around, enjoy the viewpoints and beach, and explore some of the natural surroundings.

The walks aren’t particularly long, but the heat and humidity can make them feel harder, so bring water and wear comfortable shoes.

Access can change because of weather, conservation or safety conditions, so check the latest information with Thailand’s Department of National Parks before visiting.

Visit Koh Lanta Old Town

Koh Lanta Old Town is a nice change from the beach-focused west coast and was one of my favourite stops while exploring the island.

The historic waterfront has traditional wooden buildings, small shops, restaurants and a long pier stretching out over the water.

I enjoyed spending a couple of hours walking along the waterfront and pier, browsing the small shops and stopping for a sea-view meal.

You can also visit the local museum if you want to learn more about the area’s history and community.

I’d plan to arrive around lunchtime or in the afternoon and enjoy it without rushing.

For more details on what to see and how to plan your visit, read my guide to whether Koh Lanta Old Town is worth visiting.

Explore the Tung Yee Peng Mangroves

For a different side of Koh Lanta, head to the Tung Yee Peng mangroves on the east coast.

You can explore the mangrove forest by kayak or boat, making this a nice change from the typical beach experience on other islands.

This is a slower, nature-focused experience, with a chance to learn about the mangrove ecosystem and the local community that lives around it.

Going with a local guide makes it more interesting, especially if you want to understand more about the wildlife and environment rather than simply paddle through the forest.

Allow around half a day, and consider combining the mangroves with Koh Lanta Old Town since both are on the eastern side of the island.

You may see monkeys and other wildlife along the way, but sightings aren’t guaranteed.

Don’t feed or try to attract the animals, and keep any food securely packed away.

Beach-Hop Along Koh Lanta’s West Coast

One of my favourite things about Koh Lanta was exploring its long west coast and stopping at different beaches along the way.

They are not all the same, and travelling from the busier north towards the quieter south is a great way to see how much the island changes.

In the north, Klong Dao and Long Beach are convenient if you want a good choice of restaurants and easy access to Saladan Pier.

They also make practical bases if you are staying for just a few days or don’t plan to rent a scooter.

Further south, Klong Khong and Klong Nin feel more spread out, with beach bars, smaller places to stay and plenty of spots for sunset.

Continue towards Kantiang Bay, Klong Chak and Bamboo Bay, and the coastline becomes quieter and more scenic.

You don’t need to visit every beach. I’d choose one near your accommodation for easy beach days, then explore a few others as part of a road trip around Koh Lanta.

I especially enjoyed having the freedom to stop whenever somewhere looked interesting rather than following a strict list of beaches.

Swimming conditions can change with the tide, weather and season, so don’t assume that the prettiest beach will always have the best conditions that day.

If choosing beaches is a big part of your trip, my guide to the best beaches on Koh Lanta compares them in more detail.

My tip: Don’t rush around trying to tick off every beach in one day. Choose a few beaches rather than trying to see them all.

Snorkel at Koh Rok and Koh Haa

If snorkelling is one of your priorities, a boat trip to Koh Rok and Koh Haa is one of the best day trips from Koh Lanta.

Many tours combine both areas, giving you several snorkelling stops and a full day exploring the clear waters around the national park.

Koh Rok is particularly good for combining snorkelling with beautiful beaches, while Koh Haa adds a different underwater landscape with clear water, limestone formations and its sheltered lagoon-like setting.

Most trips take a full day and include several stops, although the exact route depends on the operator and conditions.

Check whether national park fees, snorkelling equipment, lunch and hotel transfers are included before booking.

If you want to scuba dive rather than snorkel, book a dedicated diving trip instead.

Koh Haa is one of the main diving areas accessible from Koh Lanta, while dive operators also visit sites such as Hin Daeng and Hin Muang depending on your experience, conditions and seasonal access.

Take a Four Islands and Emerald Cave Tour

For more variety, consider a Four Islands tour from Koh Lanta, which typically combines several stops around the Trang islands with a visit to Emerald Cave on Koh Mook.

This is less about spending the day at one beautiful snorkelling destination and more about island hopping, swimming, snorkelling and seeing several different places.

Emerald Cave is the highlight for many visitors, as you will swim through a dark sea cave before emerging into a hidden lagoon surrounded by limestone cliffs.

If this trip appeals to you, read my guide to visiting Emerald Cave before booking, as I’ve covered the experience in much more detail there.

My tip: Choose the Four Islands tour if you prefer a varied day of island hopping and want to experience Emerald Cave rather than focusing mainly on snorkelling.

Kayak Around Koh Talabeng and Koh Phee

For a different kind of boat trip, head to Koh Talabeng and Koh Phee, two small limestone islands off Koh Lanta’s east coast.

Instead of spending the day mainly snorkelling or relaxing on beaches, these trips usually focus on kayaking beneath limestone cliffs, exploring caves and enjoying the dramatic karst scenery.

Most tours take around half a day, so this is also a good option if you don’t want to dedicate an entire day to Koh Rok, Koh Haa or the Four Islands.

I’d choose this trip if you enjoy kayaking and exploring rather than simply spending a day on a boat.

The limestone landscape also feels very different from Koh Lanta’s long west-coast beaches, making it a nice addition if you have several days on the island.

Which Koh Lanta Boat Trip Should You Choose?

Boat trip	Best for	Choose it if…
Koh Rok + Koh Haa	Snorkelling + beaches	You want a full day of snorkelling with several stops and beach time
Four Islands + Emerald Cave	Island hopping + variety	You want several islands, snorkelling and Emerald Cave
Koh Talabeng + Koh Phee	Kayaking + limestone scenery	You prefer kayaking, caves and adventure to a snorkelling-focused trip

Short on time? If you only have one or two days on Koh Lanta, I’d explore the island itself rather than spending a full day offshore. Unless snorkelling or diving is one of the main reasons for your visit.

Explore Koh Lanta on a Road Trip

One of my favourite ways to explore Koh Lanta is simply to get on the road and see where the day takes you.

The island is large and varied, so having your own transport gives you the freedom to move between beaches, viewpoints, Old Town and the quieter south.

I spent a week exploring Koh Lanta by moped, and some of my favourite moments came from being able to stop whenever somewhere looked interesting.

You can easily combine a few beaches with Koh Lanta Old Town, lunch somewhere along the way and a drive down to the southern end of the island.

You don’t need to squeeze everything into one day. Pick a few places you really want to see and leave some flexibility for unexpected stops, weather changes or a beach you decide you don’t want to leave.

If you’re comfortable riding a scooter, it’s a great way to explore independently. Otherwise, hire a driver rather than using Koh Lanta as a place to learn to ride.

For my suggested route, stops and practical tips, see my Koh Lanta road trip guide.

My tip: Don’t treat the road trip as just a way to get between attractions. Exploring the island and making spontaneous stops is part of the experience.

Other Things to Do in Koh Lanta

If you have more time, there are a few other activities worth adding depending on your interests, the weather and the season.

Explore Koh Lanta’s Caves and Waterfalls

If you have extra time and want another outdoor adventure, Mai Kaeo Cave and Khlong Chak Waterfall are two options to consider.

Mai Kaeo Cave is the more adventurous choice and is better suited to travellers comfortable with dark, enclosed spaces and a more physical experience.

Khlong Chak Waterfall is highly seasonal, so it makes more sense when recent rainfall means there’s actually water flowing.

Access and trail conditions can change, so check locally before setting out, particularly during or after heavy rain.

Visit Lanta Animal Welfare

If you love animals, you can visit Lanta Animal Welfare, a local non-profit that cares for rescued cats and dogs.

Visitor-centre tours need to be booked in advance, and your visit helps support its work. You can also shop at their store, donate or even adopt a rescue.

It’s not something everyone needs to add to their itinerary, but it can be a worthwhile stop if animal welfare is important to you.

Choose Wildlife Experiences Carefully

You’ll also find elephant experiences around Koh Lanta, but I would avoid activities involving riding, bathing, performances or close-contact photo opportunities.

If seeing elephants is important to you, look for an observation-focused experience with no direct tourist contact.

Following Giants is a no-contact experience and appears in World Animal Protection’s Elephant Friendly Tourist Guide.

My tip: Don’t add an elephant experience simply because you’re in Thailand. Choose one because you’ve researched its welfare practices and are comfortable with how the animals are treated.

Enjoy Local Food, Markets and Sunset

Food is an easy part of exploring Koh Lanta. Stop at a local restaurant during your road trip, have a waterfront meal in Koh Lanta Old Town, or finish the day with dinner and sunset on the west coast.

Local markets are also worth visiting if one happens to be running during your stay, but I wouldn’t plan an entire day around them.

If the weather isn’t cooperating, a Thai cooking class, massage or long lunch can also be a good alternative to outdoor activities.

How to Get Around Koh Lanta

Koh Lanta is a large island, so where you stay and how you get around can make a big difference to your trip.

You don’t need a scooter, but having your own transport gives you much more freedom to explore beaches, Old Town and the quieter south.

Getting Around With or Without a Scooter

If you’re a confident rider, renting a scooter is one of the easiest ways to explore Koh Lanta.

I travelled around the island by moped and loved being able to stop at beaches, viewpoints and roadside restaurants whenever I wanted.

Only rent one if you’re experienced, have the correct licence or permit, wear a helmet and have appropriate insurance.

Koh Lanta isn’t a good place to learn to ride. Read my guide to renting a scooter in Thailand before deciding.

You can definetely explore Koh Lanta without a scooter, but it will require more planning.

Stay near a beach with restaurants and everyday services, choose boat tours that include hotel pick-up, and use tuk-tuks or taxis for longer days exploring.

If you’re travelling as a family or group, aren’t comfortable riding, or simply don’t want to drive yourself, hiring a driver can be a much better option.

How Many Days Do You Need in Koh Lanta?

For most first-time visitors, 3–5 days in Koh Lanta is ideal. The island is larger than it looks, and having a few days gives you time for beaches, exploring by road and at least one boat trip without rushing.

1–2 Days in Koh Lanta

With only one or two days, focus on the experiences that matter most to you. I’d choose either a full-day boat trip or a day exploring Koh Lanta itself, with beaches, Old Town and the south of the island.

If you’re short on time, my 24-hour Koh Lanta itinerary will help you plan a realistic route.

3–5 Days in Koh Lanta

Three to five days is my recommendation for most first-time visitors. You’ll have enough time to explore the beaches, take a boat trip, spend a day discovering the island by road and add another activity such as the mangroves or diving.

For more ideas, see my 5-day Koh Lanta itinerary.

1 Week in Koh Lanta

A week is a great choice if you enjoy nature, diving, snorkelling and exploring independently.

You can see much more of the island, take a couple of different day trips and still have time for spontaneous stops and beach days.

My tip: If Koh Lanta is just one stop on a longer Southern Thailand trip, I’d aim for 3–5 days. Stay closer to a week if you want to explore the island in depth or do several outdoor and water activities.

For more ideas, see my 3 weeks Souther Thailand itinerary.

Best Time for Visiting in Koh Lanta

The time of year can affect what you can do in Koh Lanta, especially if you’re planning snorkelling, diving or boat trips to the surrounding islands.

For 2026, Mu Ko Lanta National Park lists these seasonal closures:

• Koh Rok: 1 June–30 September
• Koh Haa, Hin Daeng and Hin Muang: 1 August–30 September

These dates are set annually, so check the latest Mu Ko Lanta National Park information before planning your trip around these areas.

Weather matters too. Rough seas can affect boat trips and swimming, while heavy rain can make hiking trails muddy and waterfalls more impressive.

If outdoor activities are important to you, leave some flexibility in your itinerary so you can choose the best day for them.

My tip: If a boat trip is one of your priorities, don’t leave it until your final day. Having a flexible day gives you another chance if sea conditions aren’t suitable.
